Head?HG?Block or intake?
 

I have a big ass problem.
After i blow my y7 engine i build z6. SRP-tt-ARP head stads-ACL bearings -cometic hg.
I notched and honed block - then put all internals in. Car was ran good - with out any strange sound.. I drove it n/a till brake in... After 100mil a was in highway when at front of me cars started stops and make a traffic so i stop with them and my car shut down :l I started the car and only 3 cylinders was working - behind me was a lot of WITE smoke from my exhaust. I towing a car to the home, and take the head out. So there was nothing wrong with my new pistons :D Cometic gasket was like new - avery thing was looks good. I thought it is HG - I changed it wis OEM one. Put everything back and start the car... There was wite smoke again but all 4 cylinders was working. I take a ride for about 1 mile and come back home, after idle for 10 minutes car started work on 3 cylinders again and antifreeze come from second cylinder. So, what is wrong ??? Head ? I went to the junk yard and pick up the head , come back home , changed it and put cometic HG back in. Start the car, same ---- ! :7 Took all out again inspected the cylinders and not found anything. I looked at the intake manifold and found the antifreeze in the second spot - it is cylinder #2 ::). What you are think ? What is wrong ?I dont know what to do next - i am tired :S

coolent does run through your intake manifold, be sure your gasket is in tact and your bolting down your intake manifold in the correct sequence.

ya use a new gasket on the intake manifold.

are your sleeves cracked?

Re: Head?HG?Block or intake?
 

I checked them and they looks good to me.

I replace the block today and star the car again. Cylinder #2 not work again, and liquid was come out. CEL on and it is code 16. I replace injector - not help. ECU is bad ? or how can i fix code 16 ?

are you replacing the gasket each time? checked the head/block for flatness??
